Known issues if using Ft.Lib.pDomlette: 1. Unicode 2. does not white space normalize attributes of type NMTOKEN and ID? 3. seems to be include " " after importing external entities? Note, this version processes a DOM tree, and consequently it processes namespace nodes as attributes, not from a node's namespace axis. This permits simple document and element canonicalization without XPath. When XPath is used, the XPath result node list is passed and used to determine if the node is in the XPath result list, but little else. Authors: "Joseph M.
